DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-2 In this embodiment, a stacking tray that is easy to adjust in height and angle includes a pallet base 1. The top of the pallet base 1 is slidably connected with a positioning column 2 that penetrates into the interior thereof. The bottom of the positioning column 2 is fixed with a positioning plate 3 located inside the pallet base 1. It should be noted that the cross-section of the positioning plate 3 is circular, and the positioning plate 3 can prevent the positioning column 2 from escaping from the inside of the rotating groove. The top of the pallet base 1 is movably connected with a lifting plate 4 penetrated by the positioning column 2. It should be understood that a through hole 5 compatible with the positioning column 2 is opened on the top of the lifting plate 4. The positioning column 2 is located in the through hole 5 and is movably connected to the lifting plate 4. When it is necessary to change the direction and angle of the material parts, the purpose can be achieved by rotating the top plate 7.
[0025] In addition, the lifting plate 4 is fixed with positioning rods 6 located inside the pallet base 1 on all four sides, and the top of the positioning column 2 is fixed with a top plate 7 located above the lifting plate 4 and movably connected to the pallet base 1. It should be noted that splicing corner sills 8 are fixed with splicing corner grooves matching the splicing corner sills 8 on all four sides of the top of the top plate 7, and the bottom of the bottom plate 101 is provided with splicing corner grooves matching the splicing corner sills 8, so that the four splicing corner sills 8 are embedded in the four middle splicing corner grooves to complete the docking.
[0026] It should be noted that a plurality of resistance-increasing grooves are provided on the top of the top plate 7, and two positioning blocks 9 are fixed on the front and rear sides of the top of the top plate 7, so that the four positioning blocks 9 are inserted into the corresponding two forklift grooves or into the corresponding four splicing grooves to complete the docking.
[0027] During operation, the two height adjustment mechanisms 102 built into the pallet base 1 are synchronously adjusted to raise and lower the lifting plate 4 at the bottom of the top plate 7. The positioning slider 103 can be pushed downward so that it no longer restricts the top plate 7. The top plate 7 can rotate freely to change the direction angle of the material parts.
[0028] See also Figure 3-4 In order to adjust the height of the stacking tray, the pallet base 1 in this embodiment includes a bottom plate 101 slidably connected to the positioning column 2, and a rotating groove adapted to the positioning column 2 and the positioning plate 3 is opened on the top of the bottom plate 101. The positioning column 2 and the positioning plate 3 are both located inside the rotating groove. When the direction angle of the material parts needs to be changed, the purpose can be achieved by rotating the top plate 7, and the positioning slider 103 can be pushed downward to disengage from the positioning groove and no longer restrict the top plate 7, so that the top plate 7 can rotate freely with the positioning column 2 as the center, thereby changing the direction angle of the material parts.
[0029] It should be noted that two forklift slots are provided at the bottom of the base plate 101, and two splicing slots that are compatible with the forklift slots are provided on the left and right sides of the base plate 101. The width of the positioning block 9 is compatible with the width of the forklift slot. The stacking of two pallets can be completed by placing the base plate 101 of a palletizing tray on the top of the top plate 7, so that the four splicing corner ridges 8 are embedded in the four middle splicing corner slots, and the four positioning blocks 9 are inserted into the corresponding two forklift slots or into the corresponding four splicing slots.
[0030] Furthermore, the left and right sides of the base plate 101 are movably connected with a height adjustment mechanism 102 located inside the base plate 101 and movably connected to the lifting plate 4. It should be noted that the right height adjustment mechanism 102 includes a threaded rod 1021 rotatably connected to the rear side wall of the right inner cavity of the base plate 101 and extending to the front thereof. A twisting head 1022 is fixed to the front of the threaded rod 1021. The operator can hold the two twisting heads 1022 on both sides with both hands and twist them to drive the two threaded rods 1021 to rotate synchronously.
[0031] It should also be noted that mechanism grooves are opened on the left and right sides of the base plate 101, the threaded rod 1021 is located inside the mechanism grooves, and the four positioning rods 6 are respectively located inside the two mechanism grooves. Under the action of the threaded engagement force generated by the two rotating threaded rods 1021, the two engagement blocks 1023 on the same side are driven to move away from or closer to each other.
[0032] It should be further explained that the outer surface of the threaded rod 1021 is threadedly connected with two engaging blocks 1023, and the threaded engaging directions of the two engaging blocks 1023 are opposite. The top of the engaging block 1023 is hinged with a hinge rod 1024, and the hinge angle of the hinge rod 1024 is changed by the generated hinge force to generate a lifting force or a descending force. The side of the hinge rod 1024 away from the engaging block 1023 is hinged with a hinge block 1025 fixed to the lifting plate 4. The lifting plate 4 at the bottom of the top plate 7 is raised or lowered by the hinge block 1025, so as to achieve the effect of adjusting the horizontal height of the material parts.
[0033] In addition, the front side of the bottom plate 101 is slidably connected with a positioning slider 103 movably connected with the top plate 7. When the direction angle of the material part needs to be changed, the positioning slider 103 can be pushed downward to disengage from the positioning groove and no longer restrict the top plate 7, so that the top plate 7 can be freely rotated with the positioning column 2 as the center, thereby changing the direction angle of the material part. It should be noted that positioning grooves compatible with the positioning slider 103 are opened all around the top plate 7. When the adjustment is completed, the positioning slider 103 can pass through the linkage plate 104 to The positioning slider 103 is pushed upward by the spring 105 and is stuck in the corresponding positioning groove, thereby completing the positioning again. The back of the positioning slider 103 is fixed with a linkage plate 104 that penetrates into the bottom plate 101, and the bottom of the linkage plate 104 is fixed with a spring 105 located inside the bottom plate 101. The spring 105 is elastically deformed by being squeezed and continuously accumulates elastic force, so that when the adjustment is completed, the positioning slider 103 can be driven by the linkage plate 104, so that it is pushed upward by the spring 105 and continues to be stuck in the positioning groove.
[0034] In general, the operator can hold the two twisting heads 1022 on both sides with both hands and twist them to drive the two threaded rods 1021 to rotate synchronously, and drive the two meshing blocks 1023 on the same side to move away from or closer to each other under the action of the thread meshing force. The hinge angle of the hinge rod 1024 is changed by the generated hinge force to generate a lifting force or a descending force, so that the lifting plate 4 at the bottom of the top plate 7 rises or falls, thereby achieving the effect of adjusting the horizontal height of the material parts.
[0035] The working principle of the above embodiment is:
[0036] (1) When it is necessary to change the height of the top plate 7, the operator can hold the two twist heads 1022 on both sides with both hands. When it is necessary to increase the height, the two twist heads 1022 are twisted clockwise synchronously to drive the threaded rod 1021 to rotate clockwise. Under the action of the thread engagement force, the two engagement blocks 1023 on the same side are driven to slide forward and backward respectively away from each other. The generated hinge force changes the hinge angle of the hinge rod 1024 to generate a lifting force, so that the lifting plate 4 at the bottom of the top plate 7 rises. At the same time, the positioning slider 103 moves upward through the linkage plate 104 under the push of the spring 105 and continues to be stuck in the positioning groove to maintain the limit clamping of the top plate 7. When the height is lowered, the two twisting heads 1022 are twisted counterclockwise synchronously, so that it drives the threaded rod 1021 to rotate counterclockwise, and under the action of the thread engagement force, the two engagement blocks 1023 on the same side are driven to slide forward and backward respectively and approach each other, and the hinge angle of the hinge rod 1024 is changed by the generated hinge force, so as to generate a descending force, so that the lifting plate 4 at the bottom of the top plate 7 is lowered, and the positioning slider 103 moves downward, which drives the linkage plate 104 to move downward to squeeze the spring 105, causing it to produce elastic deformation, and the generated elasticity is converted into an upward thrust, so that the positioning slider 103 continues to be stuck in the positioning groove, maintaining the limit clamping connection with the top plate 7, thereby achieving the effect of adjusting the horizontal height of the material parts.
[0037] (2) When the direction and angle of the material parts need to be changed, the purpose can be achieved by rotating the top plate 7, and the positioning slider 103 can be pushed downward to disengage from the positioning groove and no longer restrict the top plate 7, so that the top plate 7 can rotate freely with the positioning column 2 as the center, thereby changing the direction and angle of the material parts. When the adjustment is completed, the positioning slider 103 can pass through the linkage plate 104, so that it can be pushed upward by the spring 105 and stuck in the corresponding positioning groove to complete the positioning again. The adjustment is convenient and quick.
[0038] (3) When the pallets need to be stacked, the bottom plate 101 of a pallet can be placed on top of the top plate 7, the four corner joints 8 are embedded in the four middle corner joints, and the four positioning blocks 9 are inserted into the corresponding two forklift slots or the corresponding four joint slots to complete the stacking of two pallets.
